New CEM-3 Epoxy resin copper-clad laminate using glass fabric and nonwoven glass fabric as base materials ■Features ●Excellent tracking resistance (CTI value for CEM-3 materials:600) can realize integration with power supply circuits. ●Excellent in thickness accuracy. Variations in board thickness are ±0.05 mm. This thickness accuracy is approx. 3 times higher compared with the existing composite copper-clad laminate. ●Excellent in high frequency characteristics. Small dissipation factor and thickness variations can realize designed performance. (Double-sided copper-clad) R-1786 (Single-sided copper-clad) R-1781 ●Provides dimensional stability equivalent to that of glass epoxy (FR-4). ●Reduces CO2 emission amount in our manufacturing process to one-quarter by means of our unique manufacturing process. (Compared with our conventional FR-4) ■Applications ●Liquid crystal television, PDP, PC peripheral equipment, air conditioner, plumbing equipment, power supply board, tuner, amusement machine, etc. ■Specifications(Assured values) Standard size (Warp × Fill) Thickness tolerance R-1786 Nominal thickness Warpage, Twist R-1781 Copper foil 0.018mm Copper foil 0.035mm Copper foil 0.018mm Copper foil 0.035mm 0.8mm 0.81±0.05mm 0.85±0.05mm 0.80±0.05mm Including +5 +3 1.0mm 1.00±0.05mm 1.04±0.05mm 0.99±0.05mm 1,020 ×1,025 mm −0 −0 copper foil +5 +3 1.2mm thickness. 1.15±0.05mm 1.19±0.05mm 1.14±0.05mm 1,220 ×1,025 mm −0 −0 1.6mm 1.52±0.05mm 1.56±0.05mm 1.51±0.05mm 0.82±0.05mm 1.01±0.05mm 1.16±0.05mm 1.53±0.05mm Single-sided Double-sided ≦10.0% ≦9.0% ≦7.0% ≦6.0% ≦2.5% ≦2.5% ≦2.5% ≦2.0% Note:When thickness is measured at 10 positions according to Section 5.3.3 in JIS C6481, thicknesses of at least 9 positions are within the tolerance range specified above.
